Create/Update static block programmatically in magento2

Question

I am trying to create/update static block programmatically with recurringData.php from setup script.

use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Customer\Model\GroupFactory;
use Magento\Cms\Model\BlockFactory;
class RecurringData implements InstallDataInterface
{

protected $storeManager;    
protected $_objectManager;
private  $blockFactory;
protected $_urlInterface;
protected $state;   

public function __construct(

    \Magento\Store\Model\StoreManagerInterface $storeManager,
    \Magento\Framework\ObjectManagerInterface $objectManager,       
    BlockFactory $blockFactory,
    \Magento\Framework\UrlInterface $urlInterface,
    \Magento\Framework\App\State $state
) {
    $this->storeManager = $storeManager;
    $this->_objectManager = $objectManager;
    $this->blockFactory = $blockFactory;
    $this->_urlInterface    = $urlInterface;
    $this->state = $state;
}

  public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
{
  $storeId = $this->storeManager->getStore()->getId();
   $customBlock= $this->blockFactory->create()->setStoreId($storeId)->load('test-block', 'identifier');
      $objectManager  = $this->_objectManager;   
       $media_dir = $objectManager->get('Magento\Store\Model\StoreManagerInterface')
         ->getStore()
         ->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_MEDIA);
                $Image = $media_dir."test.png";

                $contentBlock = [ 
                    'title' => 'Test Block',
                    'identifier' => 'test-block',
                    'stores' => $storeId,
                    'is_active' => 1,
                    'content' => '<div class="test-update">
                                    <h3>Static Block</h3>
                                    <div class="update-options">
                                    <div class="test-section"><a href="#"><img src="'.$Image .'" alt="">Testing</a>
                                    <p>checking data</p>
                                    </div>                                      
                                    </div>
                                </div>',
                    'sort_order' => 0
                ];
                if (!$customBlock->getId()) {
                    $this->blockFactory->create()->setData($contentBlock )->save();
                } else {
                    $customBlock->setContent($contentBlock ['content'])->save();
                }
    }
  }

Here I have already block with same identifier and i am trying to update the content of it, I am getting below error.

A block identifier with the same properties already exists in the selected store.

Am i used the correct code? Can anyone help me to implement it. Thanks

Answer 1

It seems like there are duplicate cms block available with different store. This error occurred from this file :

vendor\magento\module-cms\Model\ResourceModel\Block.php

/**
 * Perform operations before object save
 *
 * @param AbstractModel $object
 * @return $this
 * @throws LocalizedException
 */
protected function _beforeSave(AbstractModel $object)
{
    if (!$this->getIsUniqueBlockToStores($object)) {
        throw new LocalizedException(
            __('A block identifier with the same properties already exists in the selected store.')
        );
    }
    return $this;
}

Debug in this function and check identifier and block id from this $object.

Set Block Id when you update the content.

if (!$customBlock->getId()) {

     $this->blockFactory->create()->setData($contentBlock )->save();
} else {
     $customBlock->setId($customBlock->getId())->setContent($contentBlock ['content'])->save();
}

Hope it will fix your issue.
